Reactive prepolymers used as binders are produced by acrylation of oligomers, such as epoxy resins, urethanes, polyesters, silicones, oligo-buta-diene, melamine derivatives, cellulose, and starches. Prepolymers are the principal ingredients of coating formulations and largely determine the basic properties of the coating. Examples of industrially important acrylated prepolymers are in Table 5.9. 

Silicone release liners are used as a nonadhering surface to which adhesive materials, such as, for example, pressure-sensitive adhesives, can be laminated. UV curable release coatings are based on poly(dimethylsiloxane) oligomers functionalized with acrylate or epoxy groups and are mostly coated onto papers or thin films. 

Kim and colleagues copolymerized a number of PECs with oligomers of d/-lactic acid and terminated the resulting copolymer with an acrylate group to form photopolymerizable macromers. The resulting crosslinked polymers were evaluated as biodegradable lubricants for stainless steel needles and a potential substitute for the nonabsorbable silicones used presently. 

The primary chemical classes from which adhesives are made include epoxies, acrylics, phenolics, urethanes, natural and synthetic elastomers, amino resins, silicones, polyesters, polyamides, aromatic polyheterocyclics, and the various natural products such as carbohydrates and their derivatives as well as plant- and animal-based proteins. Chemical class was once a relatively clean differentiator of adhesives, but so many adhesives now are hybrids, designed to take advantage of specific attributes of more than one chemical class or type of material. Hybridization can be accomplished by incorporating into an adhesive a nonreactive resin of a different chemical class adding another type of reactive monomer, oligomer,...

Co-oligomers of fluorinated silicon containing sulfo groups [135,159] or carboxyl groups [151] have been prepared. Co-oligomerization of fluoroalkanoyl peroxides with acrylic acid and trimethylvinylsilane yielded amphiphilic oligomers soluble and surface active both in water and aromatic solvents, such as benzene, toluene, and w-xylene ...
